A V8 has a lot of low RPM torque so if you drive with a light foot it can do very well. Most of the energy from an engine is used moving the car, not engine losses. A smaller engine is always going to do better at the same load, but the difference isn’t going to be large if everything else is equal (which it often isn’t)
